you dont have to put it in chart form
choose any breed of a farm animal you wish, although it may be easier to find information on common breeds. do some research and use the information you uncover to make a chart of desired traits (y-axis) and their heritability factors (x-axis).

the chart needs to have a key explaining what the desired traits are, why they are desired, and what their heritability factors are. be sure to cite all online and print references you consult in your research.
